GEO-SFE (Structural Field Embedding)
The technique of embedding structural fields (headings, lists, schema) separately from body text — +17.3% citation lift per the arXiv paper.
Definition
Structural Field Embedding is the technique introduced in arXiv:2603.29979 of embedding a page's structural fields (title, H1, H2 hierarchy, FAQ items, schema.org @type) into the retrieval index separately from the body text, then weighting them differently in the retrieval score. Pages with strong structure benefit; flat wall-of-text pages lose. The paper reports +17.3% citation lift on the GEO benchmark.
Example
A page about 'best CRM' with proper H1/H2 hierarchy, FAQPage schema, and 6 question-form H2s embeds across multiple structural fields and gets retrieval boosts on each.How to optimize
Match the page's structural fields to query intent. Question-form H2s for informational queries. Product schema for comparison queries. VectorCite's structural-depth signal measures this directly.
